Hi all,



There is another interview problem:



Design a 1-bit fulladder using a decoder and 2 "or" gates?



Any suggestions will be appreciated! Best regards, Davy



Sounds like mid-course time for Integrated Circuits 101. This is where all that hard studying pays off.

Well, I guess you have three inputs and two outputs. Maybe you should start by drawing a truth table?

Yep. Three inputs, two outputs.

The inputs:

- the job requirements,

- the interviewee,

- the interviewer,

The outputs:

- your new office,

- the street.

In your case, when we add the three input, you're immediatly carried to the street output.

Thanks, Fred.

Well, of course I didn't mean your case, but Davy's case :-)

Thanks, Fred.
